Wrath of the Immortals Book One: Codex of the Immortals

The box set contains two books: the 128-page core rulebook titled Codex of the Immortals and a 96-page campaign setting titled The Immortals' Fury. The set also includes two poster-sized maps that go with the latter book. Both books were written by Aaron Allston, who also worked on the Rules Cyclopedia. Jeff Easley and Terry Dykstra also returned to provide the cover and interior artwork, respectively.
